Objective: To describe epidemiology of intussusception post-introduction of the rotavirus vaccine.
Methods: Hospital-based active surveillance system was set up in three tertiary care hospitals in Chandigarh and Haryana, India, to enroll children <2 y of age admitted with intussusception as per Brighton Collaboration Level-I criteria. The clinical characteristics, treatment modalities, seasonal trends, and outcome of the illness episodes were described.
Results: A total of 224 cases were reported. Majority were males (71%) and infants (69.5%). Number of intussusception was more in summer season. Location of intussusception was ileo-colic in 85% of the cases. Nearly 54% cases were treated conservatively and 46% needed surgical intervention.
Conclusion: Surveillance data provided the epidemiological description of intussusception cases post-introduction of the rotavirus vaccine in northern India. This data could be used to assess the impact of vaccine and safety with a special focus on intussusception.
